A ventilated facade is a special type of suspended ventilated structure, which consists of special facing materials. Such a facade is attached to a stainless, steel or aluminum frame to a wall or to a load-bearing ceiling. Air passes and circulates freely between the layer of cladding material and the wall, which ensures the absence of moisture and condensation on the surface of the building.

This façade system helps to retain heat in the house and eliminates dampness in the room. Thanks to the air gap, the heat transfer of the object is reduced.

Installing a ventilated façade significantly reduces the amount of building material required for the building. This significantly saves money on wall construction. Also, installing a ventilated façade significantly simplifies the entire structure, making it possible to build a larger number of floors. And the ability to install various façade cladding panels helps create classic and modern architectural designs.

Types of ventilated facades

Today on the construction market there is a huge variety of types of hinged ventilated facades.

The most popular options are:

• . This is one of the most durable and durable materials used in this area. Porcelain tiles are highly resistant to impact atmospheric precipitation and sun rays. The service life of the building is significantly increased.

• Ventilated facades made of HPL panels. An extremely popular type of finishing. HPL panels are made from compressed paper-laminated plastic. Each layer is pressed under very high pressure. Thanks to this, the panel becomes very durable, which is also used as an anti-vandal material.

• Ventilated facades made of terracotta panels. They are made from specially treated pure terracotta. This material is mainly used for finishing premium buildings.

• . Their production uses typical Russian raw materials - cement, mineral fillers, cellulose. This material gives the facade an ultra-modern look. Provides good heat and sound insulation.

• . One of best options for cladding. Metal cassettes are absolutely non-flammable.

• . Granite is most often used for these purposes. Quite a complex and expensive type of finishing. When processing stone, chips often occur on the panels, which is unacceptable when installing a ventilated curtain wall. Since chips reduce the load-bearing capacity of the fastening areas to zero. The stone is attached in a hidden way. Special cuts are made at the ends of the slabs, into which clamps (clamps) or fastening strips are inserted. Fastening elements must be made of aluminum or steel (stainless).

• . Such glazing allows you to achieve high heat and sound insulation properties, as well as aesthetic beauty. Translucent systems are extremely popular all over the world.

• Ventilated facades made of glass panels. Durable materials are used in production strained glass, which has high performance characteristics.

• . The panels have a multilayer structure: a homogeneous filler between two sheets of aluminum. To attach the filler, a heavy-duty adhesive composition is used.

• Ventilated planken facades. Planken is a facade board. This facade looks very beautiful. In addition, wood is an environmentally friendly material. When creating boards, wood of various species is used: larch, merbau, ash, meranti, sucupira, American thermal oak. Planken is often used to decorate country cottages.

• Ventilated facades made of copper panels. Such panels are very strong, flexible and durable. They are resistant to various types damage. In Russia, such ventilated facades are quite popular.

Advantages of this design

Ventilated curtain facades have the following advantages:

• This design can be quickly and easily installed at any time of the year.
• Ventilated facade systems are resistant to any weather conditions: sun, snow, rain, hail.
• Ventilated facades have high soundproofing and thermal insulation characteristics.
• During construction, you can bring to life any architectural and design ideas and use a wide range of materials for cladding: composite, brick, porcelain stoneware, planken (wooden facade board), aluminum sheet, natural stone, lath profile, fiber cement and asbestos cement sheets.
• Reducing financial costs for heating the facility.
• Possibility of using a wide range of color combinations.
• When using insulation, the “dew point” is moved beyond the load-bearing wall of the object.
• This design is durable. For 50 years, the ventilated facade does not need to be repaired (if everything was installed correctly during construction).

Construction of a ventilated curtain façade (structure)

The ventilated facade consists of several layers, like a pie. In this case, the system can be installed either with or without insulation. If it is necessary to additionally insulate the walls, then mineral wool insulation is attached to the surface of the house.

For the base, insulation based on polystyrene foam (extruded) is most often used; it does not absorb moisture and does not allow it to pass through. The gap between the surface of the insulation and the facade must be at least 40 mm. In some
In cases, it is possible to set a gap of 20 or 50 mm, but this depends on the region and type of facade. Thanks to this gap, the air, with its ascending currents, dries out the moisture that has fallen on the surface of the mineral wool or expanded polystyrene.

In order to prevent warm air from blowing out of the insulation layer, it can be covered with a special film - a vapor-tight, windproof membrane.

Regardless of the presence of insulation, the system that holds the entire structure is first attached to the wall. Next, the insulation is attached (if necessary). Then it is important to properly maintain the ventilation gap and install the outer layer of cladding made of porcelain stoneware, panels, glass, etc.

Installation of a system of suspended ventilated facades

• The brackets are installed first. They are attached to the wall using dowels or anchors. They are selected based on the size and weight of the structure. To eliminate the possibility of “cold bridges” occurring between the metal and the wall, special gaskets (most often made of paronite or plastic) are installed.

• Next, the insulation is attached to the wall using flexible connections or disc-shaped dowels. A windproof film is installed on top. Some types of insulation are produced directly with such a membrane. Which makes the work much easier.

• Now, after maintaining the air gap, the guides are attached. The frame consists of horizontal lintels and vertical posts. The guides must be level. The frame is connected using special rivets. The pitch between the guides depends on the size of the cladding panel.

• Next, the facing panel is installed. The gap between them may vary depending on the design and design of the building. Installation of facing material depends on the type of structure. The panels can be installed on special corners, clamps, and slides.

Video instructions for ventilation façade installation technology.

The birthplace of suspended ventilated facades is Germany, but the technology quickly became popular all over the world because it combines ease of installation, availability of materials used, and efficiency of the final design.

Ventilated facades are similar in design to siding, but have more advantages

What is a ventilation façade design?

The ventilated façade is metal carcass, which is also called a subsystem or under a structure. Layers of thermal insulation are laid between its elements. The outer layer of the structure is the cladding - the decorative screen can be made of steel, fiber cement, etc. There is a gap between the cladding and the thermal insulation through which natural circulation of air masses occurs.

Such facades are relevant for finishing buildings of any purpose, including those where traditional facade materials do not have a long service life - we're talking about about areas with high humidity, significant temperature fluctuations, and so on. Considering that the installation of ventilated facades can be carried out with my own hands, then the popularity of this option for finishing buildings is justified.

Ventilated facade system

Basic properties of ventilation facades

The design features, which are determined by the facade installation technology, determine the following properties:

• Mounting system- it is based on dowels, screws, fasteners, profiles, brackets. Due to the adjustment system for all these elements, there is no need to level the wall, which speeds up the finishing process.
• Insulation- can be used as an insulating layer different materials, the main requirement is non-flammability. Therefore, preference is most often given to high-density mineral wool slabs.
• Windproof membrane— its purpose is to protect the insulating layer from air flows and moisture in the environment.
• Air gap- provides the effect of a thermos, so that in such a building the costs of maintaining a comfortable microclimate are significantly lower - this applies to both heat preservation and coolness in the summer.
• Finishing- allows you to realize a design concept, while the cost of finishing can be different, due to the variety of materials used - this can be vinyl siding or metal slabs, as well as fiber cement slabs, porcelain tiles and so on.

Ventilated facade in section

Advantages and disadvantages of the design

This design has a whole list of advantages:

• Simplicity of design - you can assemble a ventilated facade with your own hands.
• Good thermal insulation makes it possible to reduce the cost of heating a building; at the same time, mineral wool insulation protects the walls from precipitation and prevents the formation of condensation.
• Thermal insulation - allows you to maintain a comfortable temperature inside the building - in the summer the room remains cool, which allows you to provide a comfortable microclimate even in the absence of air conditioning.
• Protection from wind and atmospheric moisture - it protects the walls from premature destruction, which significantly increases the service life of the building without repairs.
• Diffusion of water vapor - due to ventilation, moisture naturally evaporates from the walls of the building, which eliminates the appearance of mold, mildew, and dampness, which also makes it easier to maintain a comfortable temperature inside the building.
• Leveling temperature deformation - a large temperature difference between day and night can cause rapid destruction of a building. At the same time, the ventilated facade both naturally removes heat and prevents the building from freezing, leveling the impact of temperature fluctuations on materials, and reduces internal stress in the cladding and structural elements.

The ventilated facade reliably protects the walls from UV radiation, precipitation and cold penetration

• Fire safety - since all materials used to construct ventilated facades are non-flammable, in general such a system prevents the spread of fire.
• Additional sound insulation is an optional feature, since it is provided by a layer of thermal insulation material; on average, noise protection doubles.
• Price can be both a positive and a negative factor, since it directly depends on the materials used. Budget panels made from artificial materials provide significant savings compared to other finishing options, while the use of natural materials, in particular granite, makes such finishing quite expensive. In any case, the decorative nature of such a facade is beyond doubt.
• All-season work - compared to other options facade finishing Using “wet” methods, the installation of a ventilated façade is practically independent of weather conditions.

A ventilated façade can be installed at almost any time of the year.

Flaws:

• Fire resistance. Problems in the field of fire resistance are mainly associated with an attempt to save on insulation - the use of inexpensive polystyrene foam, which is low in cost and light in weight, makes the ventilation facade dangerous. In the presence of an open fire source, polystyrene foam burns quickly, so the use of such material for installation is unacceptable. In this design, it is necessary to use special facade polystyrene foam, which does not support combustion - this is ensured by fire retardants, which are used to foam polystyrene. Such materials are marked with an additional letter “C”, which means “self-extinguishing”. Facade polystyrene foam is designated by the letter “F” - this is the best option for the facade, since it goes out within 1 second. To prevent contact of the insulation with flame, all existing openings are framed with non-flammable basalt mineral wool slabs. This increases the complexity of installation, but is necessary to increase fire safety.
• Temperature requirements. Despite the fact that during installation of the ventilation façade they are not involved wet methods finishing, there are temperature restrictions. Installation is carried out in frost conditions no higher than -7°C. You can cover the façade with a special film and heat the resulting space with a heat gun. This increases installation costs by 15%, but without additional heating installation work are not produced, since in this case, in the next warm season, temperature fluctuations in the metal will lead to problems in fastening the subsystem.
• Vapor permeability. Choosing heat-insulating material, it is necessary to pay attention to its vapor permeability. This is necessary to remove excess moisture from living spaces. This is why materials with low vapor permeability are not the best the best choice. An example is expanded polystyrene - when using this material indoors, additional air conditioning will be required, only this will avoid dampness on the walls. If used as a heat insulator mineral wool slabs, That additional system it is not needed to remove moisture, which is the result of human activity.
• The need to install scaffolding.
• Conservatism of the construction market. Ventilated facades are still considered an innovation, so not many architects and homeowners choose this technology. This is mainly due to the traditional desire to save on the services of workers and the cost of materials - with this approach, all the advantages of a multilayer self-ventilating system disappear.

What is a subsystem: how to make the right choice?

Vertical metal subsystem for a ventilated facade

A subsystem for a ventilation façade is understood as a structure that is the basis of fasteners for both insulation and finishing panels. Depending on the material, the subsystem has different parameters and performance characteristics, which allows you to choose the appropriate option with the optimal price-quality ratio.

• Made from galvanized steel— this version of the subsystem is characterized by low weight and low cost. At the same time, the corrosion resistance is not the highest - you can only count on 25 years of operation. However, using modern systems protection against rust, you can increase the durability of such a frame.
• Made of stainless steel- this option is more expensive, but more reliable, since it can be used for at least 50 years. This design is highly durable, but is not suitable for cold climate zones, since in cold weather there is an increase in fragility.
• Made of aluminum- characterized by a high price, high quality, the low weight of aluminum allows the use of such subsystems even when restoring ancient buildings. It can be noted that this material is easy to process - it can be drilled and sawed without using complex equipment, directly at the installation site. The disadvantage is the excessive flexibility of the material, so it is not recommended for use in hot climates due to its high thermal expansion.

Having assessed the main advantages/disadvantages various materials, you can select the appropriate subsystem option. In this case, it is important to take into account the climate, the load-bearing capacity of the walls, the size of the budget and other parameters.

Types of ventilated facades

The cost of the structure and the appearance of the building directly depend on the choice of finishing material for the ventilation façade.

Exterior view of the building with a porcelain stoneware façade

A material such as porcelain stoneware allows for high precision and visual appeal of the finish. Porcelain granite demonstrates a wide range of advantages and is also environmentally friendly because it is made from kaolin clay. This natural material is an excellent natural heat insulator that protects the building from temperature changes, and is also a good sound insulator. The high density of the compressed material and firing provide impact and abrasion strength, which ensures a long service life - the facade retains its decorative effect for a long time, and the glossy surface reflects the sun's rays and protects from moisture.

Ventilated facade made of fiber cement boards

The list of advantages of fiber cement boards includes efficiency, environmental friendliness, durability, and attractive design. Fiber cement boards are available, made from natural materials, and therefore safe for others. They are characterized by a long service life, resistance to weather conditions and biological influences, so that the appearance of the building retains its attractiveness for a long time.

Other types of curtain façade

As an alternative, you can consider metal cassettes and composite panels; the most expensive and impressive option are panels made of natural stone.

Tools and equipment for installation

To properly install a ventilated facade, you must have the following tools:

1. Measuring equipment - ideally this should be a rotating laser level, which is used to mark the holes for the brackets. It is also used to align guides along all planes. Used to control installation operations building level.
2. Hammer - for drilling mounting holes.
3. Bolt gun – it is used to install façade anchors.
4. Impactless drill - necessary for installation of facing elements.
5. Riveting tool - provides fixation of profiles to the bracket, as well as other fasteners.
6. Grinder and angle grinder or metal scissors, sheet bender - for cutting and bending metal.
7. Clamps - used for preliminary fastening of guides.

How to correctly calculate a ventilated façade?

The costs of arranging the facade consist of the following items:

1. Facing material - the best option is porcelain stoneware. A façade made of metal cassettes and composites will be more expensive. If budget is not an issue, then you can use natural stone cladding. Moreover, under equal conditions, the finishing that consists of smaller tiles will be more expensive. It is also worth noting the weight of the facing material - the larger it is, the more expensive the fasteners, since special staples or high-strength glue may be needed.
2. Metal structures - their cost directly depends on the material used. The most affordable is galvanized steel, followed by painted galvanized steel, aluminum and stainless steel.
3. Facade insulation - the cost is affected not only by the material itself, but also by its thickness, which determines the cost of insulation per 1 sq. m., as well as the cost of fastenings.
4. Cost of fasteners - in addition to the above parameters of cladding and insulation, it is worth considering the material of the facade itself. The stronger the walls, the lower the cost of fastening, since in this case ordinary dowels are used. The lower the strength of the walls, the smaller the pitch of the brackets, the higher the costs.
5. Installation cost - this section includes the costs of workers, as well as assembly/disassembly of scaffolding, finishing of window and door openings.

When calculating the costs of arranging a ventilation façade, one should take into account the complexity of the façade geometry and the actual dimensions of the building. In general, the cost of 1 sq.m. a facade made of porcelain stoneware, taking into account the cost of material and installation, can start from 3,000 rubles, while the cost of installing a facade made of natural stone starts from 8,500 rubles.

Installation of a ventilated facade must be carried out according to the sequence given below in the article

It is necessary to strictly adhere to the technology for installing a ventilated facade - all work is carried out in the specified order.

Preparatory stage

• We mark the boundaries of construction work, which imply a 3 m wide strip around the perimeter of the building.
• We place all the necessary materials in this area.
• We collect forests.
• Working with the surface - assessing the curvature of the walls. If the differences do not exceed 90 mm, then there is no need to level the walls
• We carry out a study of the facade to determine the permissible load and the required thickness of the insulating material.
• Surface marking is performed in several stages. First, we mark the beacon lines - this is a horizontal line along the base and vertical lines along the edges of each wall - for this you can use a level. We mark the intermediate points at the same distance from each other - this is where the support and intermediate points for the fasteners-brackets will be located.

Frame installation

We install brackets at the marked points for fastening the frame of the ventilated facade. To do this, holes are drilled in the wall with a drill for the anchor - carefully clear them of debris and attach brackets, the length of which corresponds to the thickness of the insulation. A paronite gasket must be installed under each bracket to prevent heat loss.

Installation of thermal insulation and wind-hydroprotective membrane

Thermal insulation material is laid offset to reduce vertical joints

Mineral insulation is installed in such a way that the wall surface is completely covered. If the insulation is laid in two layers, then it is necessary to shift the subsequent one relative to the previous one by half the slab. This eliminates the coincidence of joints and the formation of cold bridges. The insulation is attached using umbrella dowels. A vapor barrier material is laid on top of the insulation.

Fastening facade slabs

Installation of porcelain stoneware on the facade

A supporting frame is mounted on top of the insulation - it is attached to the brackets. This creates an air gap between the insulation and the cladding. Installation of the supporting frame is carried out using self-tapping screws. The guides must be adjusted so that the facade system is flat. Elements for fastening the facing material are installed on top of the guides - these can be special profiles, clamps or slides. The fastening of the cladding is carried out in rows, the work is done from the bottom up.

Installation of window slopes and ebbs

When constructing slopes, fiber cement boards or HPL panels are used.

Most of the mistakes made when arranging ventilated facades are associated with attempts to save money. At the same time, customers do not take into account the consequences of these savings, which become obvious already in the first year of operation:

• Cheap porcelain stoneware slabs have low UV radiation costs, so over time the color of the facade will fade
• An attempt to save on insulation leads to the fact that the ventilated façade does not provide thermal insulation for the building and makes the façade structure a fire hazard.
• It is believed that leveling the walls when installing a ventilated facade is not required, but this is only true for those cases where the differences in the walls do not exceed 90 mm. Otherwise, the finished structure will have reduced strength. Wall differences lead to a decrease ventilation gap less than the permissible maximum minimum of 40mm. Difficulty in ventilation leads to the accumulation of condensation in the insulation - the material becomes wet, which negatively affects the heat-insulating properties. Repeated cycles of freezing and thawing cause rapid destruction of insulation.
• The gap between the facing slabs should not be less than 5 mm, and the dimensions of the seams should be the same. Violation of this requirement leads to a decrease in the decorative properties of the facade.

Hinged ventilated facades have a whole list of advantages that can only be obtained with professional installation. Therefore, it is necessary to conclude an agreement with a company that has a license, appropriate approvals and permits to carry out such construction and installation work.

Modern technologies offer quite wide choose for fast and reliable cladding house facades. One of these options is a ventilated facade, an installation technology that is quite simple, but at the same time reliable. Mounted systems protect the main structure and have additional positive characteristics.

First you need to understand what ventilated facades are and how they are equipped. This system consists of many layers that are installed in strict sequence. And there is definitely a frame on which everything rests.

For the frame it is better to use galvanized or stainless steel or aluminum. Sometimes they are replaced with wooden slats, but such material can hardly be considered durable enough.

Let's look at what layers make up a ventilated façade:

1. Vapor barrier film. Covers the entire wall first. It protects the insulation from moisture vapor from the interior. Vapors condense on the surface of the film and are removed through drainage. Thus, it has an excellent microclimate inside the house and well-protected insulation.
2. Thermal insulation material. Insulation is carried out with any material. It can be polystyrene foam, polystyrene foam or mineral wool. It allows you to retain heat inside the house.
3. Windproof and waterproofing film. In most cases it is the same material. It must be laid to protect the insulation from external atmospheric moisture.
4. The final layer will be a decorative finish, but in order for the system to be truly ventilated, a small gap of 2-3 cm must be left between the insulation and the cladding. This will ensure natural system conditioning.

If you strictly follow this plan for arranging a ventilated facade, you can be sure that you will always be comfortable in the house. And the external walls will remain reliably protected from negative influences.

Design advantages

Since this technology is becoming very popular, you need to familiarize yourself with the main positive aspects so as not to succumb to universal love. The choice should be based only on the merits of the method.

• Thermal insulation. To equip ventilated facades, insulating material is used, which allows you to retain heat in the house for a longer time, and therefore save on heating costs. It is laid in one or two layers. It all depends on the region where the house is located and on the materials from which the main frame is built.
• Soundproofing. A ventilated façade consists of many layers. They are installed in strict order so that the structure performs its functions for a long time and reliably. Thanks to this, the residents of the house will be reliably protected from external noise.
• Barrier. The outer decorative layer, as well as internal materials, which make up the entire ventilated facade system, reliably protect the walls and foundation from external destructive action. That is, from moisture, wind, temperature changes at any time of the year. In this way, you can extend the life of the house frame.
• Duration of operation. If the installation is carried out in accordance with all the rules, then hinged ventilated facades can last at least 25 years.
• Fire safety. All parts and structural elements are made from materials that either burn poorly or do not support combustion at all. Therefore, it is considered as safe as possible in this regard.
• Light weight of facing materials used for decoration.
• Aesthetics. The frame installation process is quite quick. As decorative finishing You can choose absolutely any material. This allows you to not only update and create the original appearance of your beloved home in a short period of time, but also reliably protect it from the external aggressive environment.

To everything you can add the opportunity to correct uneven walls, which could appear both during the construction process and during operation. That is why they have become so popular and are not going to give up their positions.

There are, of course, those who would like to know about the disadvantages of ventilated facades. The main disadvantage is the price. Still, it’s not so easy to cope with a large amount of work on your own. It's good if you have experience in this field.

But if you have never been involved in arranging facades, then it is better not to experiment here. This means that you need to spend extra money on paying the labor of the construction crew. And in order to securely fasten all the elements and frame, decorative finishing requires a lot of fastening materials.

Installation rules

To be sure that the hinged structure will last a really long time, you must strictly follow all installation rules. More than 80% of problems appear in the first 5 years of operation.

They are mainly due to the fact that there were some violations during the installation process. It is important to know when and not to install ventilated facades at all. It is better to refrain from the installation process if outdoors:

• Storm.
• Wind whose speed is beyond 15 m/s.
• Ice.
• Heavy fog that obstructs the view of the work area.
• The air temperature is below -20 degrees Celsius.

Preparation

At this stage, you need to do everything to ensure that the installation process goes as quickly as possible and without unforeseen situations. For this:

1. Inspect the supporting structure for strength.
2. Provide a place to store all materials.
3. Mark a danger zone for people.
4. You need to calculate the amount of all materials (frame parts, insulation, waterproofing, cladding).
5. All materials are purchased.
6. Prepare the grounds. The walls are first cleaned of finishing materials, if any, and all old fasteners, traces of dirt and human activity are removed. biological organisms, seal the holes.

Only after this can you begin installing ventilated facades.

Main stages of installation

Having familiarized yourself with all the stages, it may seem that everything is very complicated, but this is not at all the case. If you strictly follow the instructions.

• Marking for brackets. Before installing the frame, you must make markings for the guides and main brackets. To do this, use a building level (laser or water), a plumb line (vertical lines) and a level (horizontal direction). To secure the outer brackets, select an area that is located at a distance of 10–15 cm from the edge of the wall. The same nuance is taken into account for marking points near window and door openings.

• Installation of brackets. The holes for the dowels are made with a hammer drill. The size of the drill completely matches the size of the screws. But the drilling depth should be no more than a dowel. You cannot attach brackets to the seams between the materials from which the house is built.
• Installation of vapor barrier. The film is laid over the entire wall with a 10 cm overlap. The joints are taped. In places where there are brackets, the film must be cut.
• Insulation. Next, the material for thermal insulation is laid. The insulation should lie tightly, but not bulge. There should be no gaps between individual parts. The material is partially secured with umbrella dowels. If material in slabs was used for insulation, then they begin to be laid from the bottom and, moving upward, adhere to a checkerboard pattern.
• Waterproofing film. Another protective layer needs to be laid on top of the insulation. Individual sections are overlapped and taped. And they are additionally secured with dowels with a wide head, so as to attach the insulation.
• Installation of profiles. Metal profiles are fixed on brackets. This will create a ventilated gap. The profiles are fixed with rivets, but so that the part can move freely under temperature influences.
• Construction of slopes.
• Installation of decorative finishing.

It is worth repeating once again that if you follow all installation stages, then hinged ventilated facades can last a very long time.

Types of curtain-walled façade systems (SFS) of buildings

The main functional task of mounted facade systems(NFS) is long-term protection of the load-bearing walls of the building from the effects of climatic factors, reducing heat loss during the heating season, reducing noise levels and creating a highly aesthetic appearance façade of the building.

Two types of NFS are used in construction: classic and interfloor. The most popular and affordable is classical system in Moscow, installation of a ventilated façade using this system is carried out on low- and multi-storey commercial buildings and industrial facilities.

The composition of a modern ventilated facade includes:

• supporting system made of metal, consisting of brackets, profiles, clamps, shelves, slides, tables, etc.;
• durable elements for fastening the ventilated facade in the form of stainless steel rivets, anti-corrosive screws, anchor bolts;
• thermal insulation materials: polymer facade dowel, mineral insulation, paronite gaskets, wind and vapor barrier membrane;
• facing materials: porcelain stoneware, fiber cement, aluminum, composite panels and metal cassettes, HPL, etc.

A building on which a classic NFS is installed will become virtually invulnerable to both internal stress in the supporting structure and external temperature changes leading to cracks and chips, as well as other mechanical damage.

Builders install interfloor NFS on monolithic frame buildings where the walls are filled with foam or aerated concrete. This type of façade substructure is mounted with direct fastening into interfloor ceilings. Due to the fact that the density of such filling is very low, the standard installation of brackets, profiles and guides is highly undesirable here.

The fact is that high-strength concrete floors in monolithic buildings they have high load-bearing capacity. The brackets installed in them can withstand heavy loads. The suspended interfloor system is used on those buildings where it is not possible to fix other types of facade due to characteristic features walls and on objects of monolithic construction method.

The main feature of the interfloor system is the use of a welded steel bracket and a high-strength vertical profile. It is produced in the form of a pipe having a rectangular or square cross-section; a double U-shaped profile is also used.

Brackets are placed in the ceilings between floors, adhering to the minimum pitch: 150-350 mm, depending on the type of cladding panel. Massive horizontal guides are made in the form of an L - or Z - shape, and reinforced vertical profiles with a length of 1 to 5 meters are mounted on them.

Types of suspended façade systems (HFS) of buildings

The suspended facade system (HFS) is a frame structure onto which specialists install ventilated facades. Here it is necessary to take into account the correctly calculated load that will be created by the facing material chosen by the customer. Based on the type of materials used in the manufacture of the supporting structure, the NFS is constructed from:

• of stainless steel;
• aluminum and its alloys;
• galvanized steel.

Usually, before constructing and installing ventilated facades, a frame is assembled from an aluminum profile, but if cladding is required on high-rise buildings, with walls covered with heavy material such as granite or marble, it would be advisable to use the most durable steel profiles.

If the frame structure is assembled on the basis of galvanized profiles with aluminum panels as the final finishing of the facade, then this solution can be considered almost eternal. Of course, external erosion will cause NSF over several decades, but the entire period during which all this will happen will exceed the guaranteed service life of the building by a margin.

The customer has the right to choose, based on his preferences, both the type of material on which the curtained façade will be stable and durable, and cladding panels that have their own specific technology for fastening to the NFS.

Mostly, in practice this happens:

• fastening with galvanized screws;
• fixation with hidden clamps;
• the use of special adhesive solutions.

Despite the standard installation technology, the specifically selected NFS is strictly individual project for almost all types of buildings. The undoubted advantage of modern NFS is the unique opportunity to carry out installation directly on the outer walls of the building. It is noteworthy that there will be no need to repair external walls if they are reconstructed, which significantly reduces the cost of operating the structure.

Installation of NFS can be carried out regardless of the time of year, with strict adherence to environmental safety standards adopted in Russia, compliance monitoring building regulations, with the necessary quality certificates.

Features of installation and installation of ventilation facades

When choosing a fastening system for customers to install ventilation facades in Moscow and the Moscow region, specialists from the Alpika construction company try to take into account the importance of the following factors:

• the diameter of the anchors, the size of the embedment depth directly depend on the building material of the walls, on the amount of force on the brackets;
• correct selection of fasteners will help prevent deformation of load-bearing walls;
• a thermal break is installed at the places where the brackets are fixed to reduce heat transfer;
• at the time of fastening the brackets, additional fasteners are laid for window slopes and ebbs.

Vertical profiles in the installation of ventilated facades in Moscow are the basic basis for fastening the cladding.

The use of vapor-permeable, wind- and moisture-proof film in the installation process, together with a heat insulator, should be treated with great caution: it is a fire hazard. Now they are producing new types of insulation that do not require film.

For reliable and long-term operation of the fastening system for ventilated facades, it is necessary to correctly calculate the load distribution along the entire length of the fastening components.

Stages of installation of a ventilated facade

Installation of brackets

On the prepared wall, according to the project, the attachment points for the metal supporting frame are marked. At the designated points, holes are drilled for anchors. The drill must be calibrated so that the holes in depth and diameter exactly match the anchors used. After this, brackets are attached to the holes cleared of debris using façade anchors. The length of the bracket is selected based on the thickness of the insulation. A paronite gasket is installed between the bracket and the wall to prevent heat loss.

Attaching the insulation

After installing all the brackets, mineral insulation is installed, which should cover 100% of the wall surface. Rows of insulation boards are installed in a dressing. If insulation is carried out in several layers, then the slabs of each subsequent layer are also installed offset with respect to the previous layer so that the joints do not coincide. Umbrella dowels are used to attach the insulation. If necessary, a vapor barrier material is attached to the installed insulation.

Installation of the supporting frame

Guides are mounted to the brackets at a certain distance from the insulation using self-tapping screws, after which the plane of the façade system is adjusted. Fastening elements for the facing material are installed on the guides. These can be clamps, slides, or a special profile.

Frame cladding

The cladding material is attached in rows from bottom to top onto the installed and adjusted subsystem in accordance with the technology. Using fasteners, the material is securely fixed to the guides.

The cost of installation of a ventilated facade

Today's prices for installing ventilation facades can be significantly optimized if you contact a licensed, experienced company. The cost takes into account engineering and survey activities, the actual wear and tear of the building’s surface, and its number of floors.

The price of this type of service may be affected by the characteristics of the future curtain ventilated façade: “warm” or “cold”, completion time.

Finishing using ventilated facade systems begins with the installation of a frame subsystem. Mistakes at this stage can result in the cladding not performing its functions correctly and even completely destroying the finish. Let's talk about frames for independent ventilation facades and the features of their installation and assembly.

Functions of the façade frame

The curtained ventilated façade is conceptually derived from the external glazing systems of high-rise buildings, from which it inherits its technological complexity. The high versatility of this finish is achieved due to a very specific fastening subsystem, which performs a number of target functions.

The main one is to distance the facing panels from the load-bearing wall and the insulating layer to obtain a space in which street air circulates freely. This is one of the most effective ways protection of insulation materials with high hygroscopicity. Over half a century of active implementation, this method has proven itself only with the best side. Due to the external cladding, the temperature exchange of the building is normalized: in summer the sun heats the walls less, and in winter the air layer prevents the diffusion outflow of heat.

1 - protection of the building from heating; 2 - protection of insulation and structure from precipitation; 3 - ventilated facade subsystem; 4 - vapor-permeable membrane; 5 - insulation; 6 - removing moisture from the room

At first acquaintance, the system demonstrates obvious complexity and creates the illusion of unreliability. This leads to the second key function of the frame - to protect the insulation and supporting structure without compromising the integrity of the cladding and its appearance. This becomes possible due to the high resistance of individual frame elements to mechanical stress and proper load distribution.

We can conclude that such high technology is very expensive, both in terms of economic accessibility and in terms of installation complexity. Therefore, the third task that is set for the frames of independent ventilation facades is a high degree of unification of components. This not only makes it possible to carry out work as quickly as possible with a high degree of participation in expensive industrial mountaineering. The frame for ventilated facades can be adapted even to very complex architecture, including surfaces with deviations from the vertical.

Types of subsystems for ventilated facades

Today there is a very wide range of frame systems for ventilated facades, each of which is designed to work in specific facility conditions with a specific type of finishing material. To classify them, you need to pay attention to two key features.

The first is the frame material:

1. Cink Steel. Optimal for facade systems without claims to durability in favor of cost savings. Most often used in the construction of inexpensive aluminum and polyurethane facade cladding with the prospect of replacing them.
2. Stainless steel. Frames made from it are the most durable and are used for cladding. high-rise buildings using heavy panels (once and for a long time).
3. Aluminum substructure. It is used in restoration and insulation projects of old buildings, where the permissible load on the load-bearing walls. Disadvantage - low fire safety, aluminum subsystems are not used in high-rise construction.
4. Hydrophobized wood. Used as rack elements in low-rise construction and regions with mild climates.

Second hallmark- manufacturer frame system. Elements from different brands are not comparable to each other (with very rare exceptions), so they are always supplied as a set. The choice in favor of a specific manufacturer is determined mainly by the convenience and manufacturability of installation. This is almost unimportant for a private developer, but with the involvement of industrial climbers on large-scale projects, the need to additionally drill or trim anything results in dozens of extra man-hours.

Frame configuration for curtain façade

The third key difference is the form factor of the finished frame system. It depends entirely on the format of the cladding used, and every self-respecting manufacturer considers it their duty to support all three types in its assortment. In addition, if the manufacturer of the cladding materials provides a warranty on them, installation should only be carried out on a subsystem of the recommended type. Based on form factor, frame systems are divided into:

• vertical orientation: for horizontal siding and continuous preparatory sheathing with slab materials;
• horizontal orientation: for vertical siding, magnesite and polyurethane panels;
• cross type: for marble, brick, porcelain stoneware and other heavy panels.

Before proceeding with installation, study routing and an album of technical solutions for a specific product. The goal is to establish the assembly order and operation of the connecting nodes. Fortunately, almost all manufacturers have the same mapping scheme and package contents. They have stationary brackets that are directly attached to the wall, and a movable profile that, together with the first element, forms a base console. The movable bar has a standard method of connection with the rack elements of the frame, plus the kit may include connectors for extending racks, corner and cross connectors.

Beginning of installation: preparing the wall and attaching the consoles

Installation begins with preparing the walls: removing the remains of the destroyed finish and antiseptic treatment if there are signs of mold damage. The installation of consoles begins from the top row, installing them in increments normalized by the type and weight of the cladding. Installation is carried out on a plastic lining, which prevents heat migration between the wall and the frame, fastening is carried out with anchor bolts, and in the case of loose and hollow bases - with chemical anchors or special types dowels (KAT, KVT). Then, from each bracket, a plumb line is thrown along the wall, along which holes are drilled and the remaining elements of the vertical row are installed.

Many manufacturers distribute the mounting holes in the consoles so that they can be mounted as an assembly, which significantly speeds up the work. After fastening, the movable planks of the upper row consoles are lined up in a common line according to the curvature of the wall plane. Then the plumb line is hung on the edge of the upper console and the remaining sliding parts are adjusted and secured in this way. To secure the retractable strip, both bolted connections and blind rivets can be used.

If the subsystem is assembled with horizontal orientation of the rack elements, the method of adjusting the consoles remains the same, but the brackets are turned in a different direction. In this way, first the outermost vertical rows are installed, along the elements of which a fishing line is then stretched to align the intermediate brackets of the horizontal row.

Assembling the system of fastening profiles

Sometimes it is recommended to fix the consoles after fixing the racks of the frame system. If this is the manufacturer's recommendation, this is quite acceptable. However, plumb alignment is considered the preferred method if there are no additional installation requirements.

The profile usually has standard means of preliminary fastening, represented by grooves and latches. After fixing at the installation site, the rack elements are secured along the internal shelf to the retractable console bar using bolts, rivets or non-hardened screws.

Most “branded” systems require the installation of fastening profiles after installing the insulation and windproof membrane/film. It is, however, possible to lay thermal insulation mats not only under the sheathing, but also between the racks. In this case, a windproof film is rolled out over the profiles and a system of spacer slats with vertical or two-layer cross orientation is assembled.

To conclude our review, we note that the basement and façade parts of the wall are separated by a horizontal ebb strip. This addition is designed to limit the flow of moisture-saturated air from the foundation into the space of the main vent and prevent the entry of water - condensation and slanting rain - into the basement part. Thus, air convection in the two zones occurs separately.
